Chryso unveils CHRYSO®Quad, the first comprehensive range of admixtures and services for using challenging sands and effectively use of local resources
The quality and availability of the aggregates used for concrete - especially sand - is a major challenge for the construction industry, particularly quarry companies and ready-mix concrete professionals (RMC). The new CHRYSO®Quad admixture solutions provide an answer to use challenging sands, including low or high fines content, swelling clay and shape factors. CHRYSO®Quad is a specific comprehensive range of products and services for producing concrete matching the required performance criteria.
CHRYSO®Quad solutions enhance the quality of concrete featuring challenging sands, but also promote sustainable development and reduce costs by sourcing resources from local suppliers, streamlining the procurement process and lowering the carbon footprint.
CLEAR and GRAFT technologies tailored for all types of challenging sands
Based on 10 years of R&D efforts focusing on developing special polymers, CLEAR® (Clay Enabling Admixture Response) and GRAFT (Gap GRAdation Fixing Technology) technologies bring even greater structure to the CHRYSO®Quad range.
- The CLEAR technology specifically targets excess of fines and swelling clay problematics, by helping to disperse the binders and reduce viscosity.
- The GRAFT technology addresses the issue of low fines content and specific shape factors, while improving concrete cohesiveness and finishing.
Dedicated services to satisfy every customer requirement
CHRYSO accompanies its admixture solutions with innovative services, including the CHRYSO®Quad Lab diagnostics tool for reliably and quickly characterising sand based on three criteria (fineness modulus, type of sand and absorption).
Chryso has also built on its expertise by launching and patenting the new in-situ CHRYSO®CLEAR Test for swiftly quantifying the swelling clay content.
After field testing and analysing the sand, CHRYSO's technical experts provide tailor-made CHRYSO®Quad admixture solution, which can be tailored to reflect changes in available resources.
A solution to address environmental considerations and reduce costs
Reducing the environmental impact is a major challenge faced by concrete manufacturers and quarry companies. Implementing an extended range of sands and incorporating challenging sands is consistent with an eco-friendly approach to concrete design. It improves the use of local resources, optimizes procurement costs and lowers CO2 emissions. The CHRYSO®Quad solution fosters circular economy and offers a best-fit response to economic and environmental needs.
